Questions about this product
- What are the main applications for this molded case circuit breaker?
- It's specifically built to protect solar PV string combiner boxes and large battery banks. The breaker safely isolates individual panel strings or acts as a main safety switch for high-current DC storage. This prevents costly damage by isolating electrical faults before they spread.
- How do I choose between the 150A and 250A options for my system?
- Select the rating based on your system's continuous load and the maximum current your wiring can safely handle. The 150A model works well for medium-sized solar arrays or battery setups. Choose the 250A version if you are running larger commercial strings or high-capacity battery banks.
- What are the maximum voltage and interrupting ratings for this DC breaker?
- This single-pole breaker safely handles an operational voltage up to 1000V DC and an insulation voltage of 1200V DC. It features a typical ultimate breaking capacity of 25 kA to stop severe short circuits. Do not exceed these limits or try to use this specialized DC unit on AC systems.
